Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0017] like Figures 1 to 4 As shown, this application provides a height adjustment device for a lumbar cistern drainage bag, comprising: a support rod assembly 10, a height adjustment assembly 20, and a drainage bag hanging component 30. The support rod assembly 10 and the height adjustment assembly 20 are movably connected, and the drainage bag hanging component 30 is connected to the height adjustment assembly 20. The support rod assembly 10 includes a support rod 11 and at least one gear rail 12, the gear rail 12 being fixedly connected to the support rod 11 along the axial direction X. The height adjustment assembly includes a mounting housing 21, a driving component 23 for the drainage bag hanging component 30, and at least one gear 24. The drainage bag hanging component 30 is connected to the mounting housing 21 for suspending the lumbar cistern drainage bag. The driving component 23 is installed inside the mounting housing 21. The gear 24 is connected to the driving component 23 and meshes with the gear rail 12. The driving component 23 drives the gear 24 to rotate, thereby causing the height adjustment assembly 20 to move along the axial direction X of the support rod 11.

[0018] Specifically, such as Figure 1 As shown, the support rod assembly 10 and the height adjustment assembly 20 are movably connected. The support rod assembly 10 provides support for the height adjustment assembly 20, which moves along the axial direction X of the support rod assembly 10. The support rod assembly 10 includes a support rod 11 and at least one toothed rail 12. The toothed rail 12 is fixedly mounted on the support rod 11 and installed along the axial direction X of the support rod 11.

[0019] In some embodiments, the outer surface of the support rod 11 is provided with scale lines to facilitate precise adjustment of the height adjustment component 20 by medical personnel. In addition, the support rod 11 is a rigid component that can provide sufficient support force. The component can be a cylindrical steel pipe, a rigid plastic column, etc., and the embodiments of this application do not limit it.

[0020] The height adjustment assembly 20 includes a mounting housing 21, a drive component 23, and at least one gear 24. A drainage bag attachment component 30 is connected to the mounting housing 21 to suspend the lumbar drainage bag, allowing the bag to move with the housing 21. The drive component 23 is installed inside the housing 21 and is connected to the gear 24 to drive its rotation. After the gear 24 meshes with the gear rail 12, the drive component 23 drives the gear 24 to rotate, causing it to move along the gear rail 12, which in turn drives the height adjustment assembly 20 to move along the axial direction X of the support rod 11.

[0021] In some embodiments, the toothed rail 12 can be a single toothed rail 12, which can be installed on the outer surface of the support rod 11. The side wall of the mounting housing 21 has a through hole. The gear 24 is connected to the drive component 23 and passes through the through hole on the housing 21 to mesh with the toothed rail 12. When the drive component 23 drives the gear 24 to rotate, the gear 24 moves along the toothed rail 12, which drives the height adjustment component 20 to move along the axial direction X of the support rod assembly 10, and then drives the drainage bag hanging component 30 to move along the axial direction X of the support rod assembly 10.

[0022] During use, the support rod 11 is fixedly installed on the infusion stand, which can be done by plugging or connecting with auxiliary components, etc., and this application embodiment does not limit the method. Then, the drainage bag is hung on the drainage bag hanging component 30. When medical staff need to adjust the height of the drainage bag, they only need to adjust the drive component 23. The drive component 23 drives the gear 24 to rotate, so that the gear 24 moves along the gear rail 12 in a certain direction in the X direction, which further drives the height adjustment component 20 to move along the gear rail 12. This can adjust the movement of the drainage bag hanging component 30 in the axial direction X of the support rod assembly 10, thereby adjusting the height of the drainage bag in the axial direction X of the support rod assembly 10.

[0023] In this embodiment, the height of the drainage bag is adjusted by using a drive component 23 in conjunction with a gear 24 and a gear rail 12. The device has a simple structure, and compared to related technologies that manually adjust the height of the lumbar cistern drainage bag, such as multi-link or worm gear adjustment structures, it reduces a large number of intermediate transmission components and complex connection structures, lowers manufacturing and assembly difficulty, and improves the overall structural stability. Furthermore, the use of gear 24 and gear rail 12 for height adjustment allows for reasonable layout and design according to actual space requirements, enabling height adjustment of the lumbar cistern drainage bag within limited space. This is particularly suitable for equipment or scenarios with high space requirements. During operation, the drive component 23 drives the gear 24 to rotate, thereby moving the drainage bag attachment component 30 to adjust the height. The operation process only requires controlling the start, stop, and direction of the drive component 23, enabling rapid adjustment without multiple cumbersome steps, greatly simplifying the operation process and reducing the time and effort required by medical personnel. Furthermore, the meshing transmission of gear 24 and toothed track 12 has a precise transmission ratio. By rationally designing parameters such as the module and number of teeth of gear 24 and the tooth pitch of toothed track 12, precise height adjustment can be achieved, keeping the error within a very small range and improving the accuracy and reliability of the entire height adjustment device.

[0024] Optional, such as Figures 1 to 4 As shown, the support rod 11 has a hollow structure, and the support rod 11 has at least one long groove 111 along the axial direction. The toothed rail 12 is installed on the inner side wall of the support rod 11.

[0025] Specifically, the support rod 11 is provided with a hollow structure, which can be a cylindrical or hexagonal prism hollow structure, and this application embodiment does not limit it. At least one long groove 111 is opened in the support rod 11 along the axial direction X. The height of the long groove 111 is the same as the wall thickness of the support rod 11, and the length of the groove 111 is the same as the length of the support rod 11. The gear rail 12 is installed on the inner side wall of the support rod 11 where the long groove 111 is located. The width of the long groove 111 is greater than the sum of the thickness of the gear rail 12 and the diameter of the gear 24 by a preset value, so that the gear 24 is placed radially into the long groove 111 and meshes with the gear rail 12, and can move along the axial direction X of the support rod 11 under the drive of the drive component 23.

[0026] It is understandable that designing the support rod 11 as a hollow structure can further reduce the weight of the entire lumbar sac drainage bag height adjustment device without affecting its basic mechanical properties, making it more convenient to install and use, and easier for medical staff to access. At the same time, creating a long slot on the support rod 11 and installing the toothed rail 12 on the inner wall of the support rod 11 can further make the entire device more compact and rational, reducing the device's volume footprint.

[0027] Optional, such as Figures 1 to 4As shown, there are two long grooves 111, which are arranged radially opposite each other on the support rod.

[0028] Specifically, two long slots 111 are provided, which are arranged radially opposite each other on the support rod to provide more possibilities for the installation of other components in the height adjustment assembly 20. Other components in the height adjustment assembly 20 can pass through the two long slots 111 of the support rod 11, or toothed rails 12 or other support components can be set in the two long slots 111 respectively to further compact the layout of each component.

[0029] In some embodiments, two toothed rails 12 are also provided. The two toothed rails 12 can be arranged side by side on the inner wall of the support rod 11 and located on the same side of the two long slots 111. The tooth surfaces of the two toothed rails 12 are equidistant from the axis of the output shaft of the drive component 23. Correspondingly, two gears 24 are also provided. One gear 24 meshes with one toothed rail 12. The drive component 23 drives the two gears 24 to rotate at the same time, so as to provide stronger transmission power for the height adjustment component 20 and make the force on the support rod 11 more uniform, avoiding twisting or deformation caused by unilateral force.

[0030] In other embodiments, a toothed rail 12 can be installed on the inner wall of the support rod where the long slot 111 is located, and a slide rail can be installed on the inner wall of the support rod 11 where the other long slot 111 is located. One side of the mounting housing 21 meshes with the toothed rail on the long slot 111 via a gear 24, and the other side of the mounting housing 21 is slidably connected to the slide rail. When the toothed rail 12 of the long slot 111 meshes with the gear 24, the driving component 23 drives the gear 24 to rotate, thereby moving the height adjustment component 20 along the toothed rail 12 and simultaneously sliding it along the slide rail on the other long slot 111. The slide rail provides stable support and guidance for the height adjustment component 20, reducing swaying and offset during movement. When the toothed rail 12 on the long slot 111 and the gear 24 work together to drive the height adjustment component 20, the slide rail on the other long slot 111 ensures the stability of the height adjustment component 20 in other directions, making the entire movement process smoother and improving the accuracy and reliability of motion control.

[0031] It is understandable that having two radially opposite long grooves 111 on the support rod 11 can provide two opposite force points for the connection of the height adjustment component 20 on the support rod. When the drive component 23 cooperates with the gear 24 and the gear rail 12 to drive the height adjustment component 20 to move along the axial direction X of the support rod 11, the force is more evenly distributed along the edge and surrounding area of ​​the long groove 111. Compared with a single groove structure, stress concentration in a local area can be avoided, reducing the risk of deformation or breakage of the support rod 11 due to stress concentration.

[0032] Optional, such as Figures 1 to 4As shown, the mounting housing 21 includes two first through holes 27 arranged opposite to each other. The support rod assembly 10 passes through the two first through holes 27 to be movably connected to the height adjustment assembly 20. The two first through holes 27 are respectively opened on both sides of the mounting housing 21 perpendicular to the long groove 111.

[0033] Specifically, a first through hole 27 is opened on each of the two sides of the mounting housing 21 perpendicular to the long groove 111. The inner diameter of the first through hole 27 is larger than the outer diameter of the support rod assembly 10 by a preset value, such as 0.5mm, 0.6mm, etc., which can ensure that the support rod 11 can pass through the first through hole 27. This embodiment does not limit it, so that the support rod assembly 10 can pass through the two first through holes 27 and the mounting housing 21 can be fitted onto the support rod 11.

[0034] Understandably, by opening a first through hole 27 on each of the two perpendicular holes of the mounting housing 21 and the long groove 111, allowing the mounting housing 21 to be fitted onto the support rod 11, the structure of the entire waist pool drainage bag height adjustment device can be made more compact, reducing the overall volume of the device. Simultaneously, after the mounting housing 21 is fitted onto the support rod 11, the freedom of the mounting housing 21 in the horizontal and other directions is restricted by the support rod 11, allowing it to move only within the range permitted by the support rod 11 along the axis of the support rod 11. This reduces the uncertainty of the height adjustment component during operation and enhances the stability and reliability of the entire structure.

[0035] Optional, such as Figures 1 to 4 As shown, the driving component 23 includes a driving body 231 and a driving rod 232. The driving body 231 drives the driving rod 232 to rotate. One end of the driving rod 232 is connected to the driving body 231, and the other end of the driving rod 232 passes through two long slots 111 and is rotatably connected to the mounting housing 21. A gear 24 is fixedly connected to the driving rod 232, and one gear 24 meshes with a toothed rail 12.

[0036] Specifically, the driving component 23 includes a driving body 231 and a driving rod 232. The driving body 231 can be a linear motor, servo motor, etc., and this embodiment does not limit its use. The driving body 231 is fixedly installed at the bottom of the mounting housing 21 at the position corresponding to the long slot 111 on one side. The external power cable of the driving body 231 is laid along the inside of the support rod 11 and a power plug is provided. In use, medical personnel connect the plug to the power supply to provide power to the driving body 231. One end of the driving rod 232 is connected to the driving body 231, and the other end of the driving rod 232 passes through the two long slots 111 and is rotatably connected to the other side of the mounting housing 21. The gear 24 passes through the position of the driving rod 232 corresponding to the gear rail 12 and rotates under the drive of the driving body 231. The connection method between the driving body 231 and the driving rod 232 can be a bearing connection or a welding connection, etc., to ensure a stable connection between the driving body 231 and the driving rod 232, and that the driving body 231 can drive the driving rod 232 to rotate. This embodiment does not limit its specific connection method. The difference between the inner diameter of the mounting housing 21 and the outer diameter of the support rod 11 on the same side as the two long grooves 111 is greater than a preset value, so that the drive rod 232 cooperates with the side walls of the mounting housing 21 and the long grooves 111 perpendicular to each other and parallel to the axial direction of the support rod 11, providing a force to the gear 24 toward the gear rail 12, so that the gear 24 and the gear rail 12 mesh more tightly, and ensuring the stability of power transmission during height adjustment.

[0037] The drive component 23 includes a drive body 231 and a drive rod 232. The drive rod 232 passes through two long slots 111 and is fixedly connected to the gear 24. When the drive body 231 drives the drive rod 232 to rotate, it drives the gear 24 to rotate. This layout is compact and reasonable, making full use of the space of the support rod. It can further realize the miniaturization and weight reduction of the waist pool drainage bag height adjustment device, reducing additional connecting parts and installation space.

[0038] In some embodiments, there are two gears 24. A toothed rail 12 can be installed on the inner sidewall of the support rod 11 at the opposite positions of the two long slots 111. The two gears 24 are respectively fixedly installed on the drive rod 232 at positions corresponding to the toothed rails 12, so that one gear 24 meshes with one toothed rail 12. When the drive body 231 drives the drive rod 232 to rotate, the two gears 24 rotate synchronously with the drive rod 232, thereby driving the height adjustment component 20 to move in the axial direction X of the support rod 11. By having a drive body 231 cooperate with the drive rod 232 to simultaneously drive the two gears 24 to rotate, so that the two gears 24 move synchronously on the two toothed rails 12, the overall structure of the device can be further simplified, providing two synchronous transmission forces for the height adjustment component 20, enabling the device to withstand greater loads, and further improving the stability of the device.

[0039] In other embodiments, the gear 24 has one slot 111. A toothed rail 12 can be installed on the inner wall of the support rod 11 at a position opposite to the slot 111. The gear 24 is fixedly installed on the drive rod 232 at a position corresponding to the toothed rail 12, so that the gear 24 meshes with the toothed rail 12. When the drive body 231 drives the drive rod 232 to rotate, the gear 24 rotates synchronously with the drive rod 232 to drive the height adjustment component 20 to move in the axial direction X of the support rod 11. A slide rail can be provided at the location of the other slot 111. A slider is rotatably connected to the drive rod 232 at a position corresponding to the slide rail. The slider is slidably connected to the slide rail. When the drive body 231 drives the drive rod 232 to rotate, the slider does not participate in the rotation. When the drive body 231 drives the drive rod 232 to rotate, it drives the gear 24 to rotate, so that when the gear 24 moves along the toothed rail 12 at the location of one slot 111, the slider moves synchronously along the slide rail on the other slot 111 to achieve adjustment of the height adjustment component 20 in the axial direction X of the support rod. A toothed rail 12 and a gear 24 are installed on one long groove 111 to provide power for the movement of the height adjustment component 20. A slider and a slide rail are installed on another long groove 111 to provide stable support and guidance for the movement of the height adjustment component 20. Both the slider and the gear 12 are connected to the drive rod so that they move synchronously, reducing shaking and deviation during the movement and making the movement process smoother.

[0040] In other embodiments, a pre-set long groove along the axial direction X of the support rod 11 is provided in the hollow portion of the support rod 11. There can be three toothed rails 12, respectively located in two long grooves 111 and the pre-set long groove. Correspondingly, three gears 24 are also provided, passing through the drive rod 232 at the position corresponding to the toothed rail 12. The gears 24 mesh with the toothed rails 12, and the drive body 231 simultaneously drives all three gears 24 to rotate, so that the three gears 24 move simultaneously along the three toothed rails 12. This provides three transmission forces to the height adjustment component 20 simultaneously, further enhancing the support force on the height adjustment component 20. It should be noted that the number of toothed rails 24 and gears 12 can be set according to actual needs, and this application embodiment does not limit them.

[0041] Optional, such as Figures 1 to 4 As shown, the drainage bag hanging component 30 also includes an extension rod 26 and a hanging member 220; a second through hole 211 is opened on one side of the mounting housing 21 opposite to the long groove 111, one end of the extension rod 26 is connected to the hanging member 220, and the other end of the extension rod 26 passes through the second through hole 211 and the two long grooves 111 and is fixedly connected to the other side of the mounting housing 21.

[0042] Specifically, the drainage bag hanging component 30 also includes an extension rod 26 and a hanging member 220. The hanging member 220 is used to hang the drainage bag. One end of the extension rod 26 is connected to the hanging member 220, and the other end passes through the second through hole 211 and the two long slots 111 opened opposite to the mounting housing 21, and is fixedly connected to the other side of the mounting housing 21. The extension rod can be a metal rod, a rigid plastic rod, or other non-deformable structure, and this application embodiment does not limit it.

[0043] Understandably, the drainage bag is hung on the connector 220, which is connected to one end of the extension rod 26. The other end of the extension rod 26 passes through the two long slots 111 of the mounting housing 21 and the support rod 11 and is fixedly connected to the mounting housing 21. Compared to directly hanging the drainage bag on the mounting housing 21, the load of the height adjustment component 20 can be distributed more evenly, reducing the pressure on individual components, avoiding excessive local stress, and ensuring the stable operation of the entire device. At the same time, setting the extension rod 26 to hang the drainage bag increases the support structure for the drainage bag to a certain extent. When the support rod 11 is subjected to external interference or vibration, the extension rod can play a certain role in buffering and balancing, enhancing the overall anti-interference ability and stability of the device.

[0044] Optional, such as Figures 1 to 4 As shown, the mounting bracket 220 includes a sensor light 221 and a hook 222; one end of the sensor light 221 is connected to the extension rod 26, and the other end of the sensor light 221 is connected to the hook 222.

[0045] Specifically, the mounting bracket 220 includes a sensor light 221 and a hook 222. The sensor light 221 can be an externally powered light fixture, with its power cord passing through the second through hole 211 along the extension rod 26 and connecting to the power cord of the drive component 23 to provide power to the sensor light 221. The hook 222 is used to hang the drainage bag. The sensor light 221 automatically turns on when the external ambient lighting is dim or when medical personnel approach, making it easier for medical personnel to observe the drainage bag. The sensor light 221 can also automatically adjust its brightness according to the ambient light, further improving the user experience for medical personnel. Of course, the sensor light 221 can also be a battery-powered sensor light, eliminating the need for wiring to connect to an external power source; this embodiment does not limit its use.

[0046] In some embodiments, the sensor light 221 has an opening, one end of the hook 222 is movably connected to the sensor light 221, and the other end of the hook 222 can be hung in the opening on the sensor light, so as to make the hanging of the drainage bag more stable and safe, and prevent the drainage bag from falling off the hook 222 due to the impact or instability of the support rod 11.

[0047] In this embodiment, the mounting bracket 220 includes a sensor light 221 and a hook 222. The sensor light 221 automatically turns on when the lighting is dim or when medical staff approach, providing sufficient illumination for medical staff to observe the drainage situation or change the drainage bag, eliminating the need to find additional lighting equipment, improving operational efficiency, and reducing operational errors caused by insufficient light. At the same time, the soft sensor light meets the needs of medical staff operations without disturbing the patient's rest like strong light. For patients who need to stay in bed for a long time and are in a relatively quiet environment, the sensor light design helps to create a comfortable treatment environment and reduce the patient's anxiety.

[0048] Optional, such as Figures 1 to 4 As shown, the height adjustment device for the lumbar drainage bag also includes a gravity sensor 13; the gravity sensor 13 is electrically connected to the drive component 23, and controls the height adjustment component 20 to move along the axial direction X of the support rod 11 by detecting the weight change of the drainage bag hanging component 30.

[0049] Specifically, the height adjustment device for the lumbar drainage bag also includes a gravity sensor 13, and the drive component 23 includes a controller. The drive component 23 is electrically connected to the controller, and the controller is electrically connected to the gravity sensor 13. The gravity sensor 13 is used to detect changes in the weight of the drainage bag hanging component 30. When the gravity sensor 13 detects a change in the weight of the drainage bag hanging component 30, it transmits the weight information to the controller. The controller controls the drive component 23 according to preset rules, and the drive component 23 controls the rotation of the gear 24, thereby adjusting the height of the drainage bag hanging component 30 along the axial direction X of the support rod 11.

[0050] It is understandable that a gravity sensor 13 is installed in the height adjustment device of the lumbar drainage bag. The gravity sensor 13 can sense the gravity change of the drainage bag in real time and realize intelligent control through the preset rules of the controller. It can automatically adjust the height of the drainage bag hanging parts in a timely manner according to the preset correspondence between gravity and height, so that the drainage bag is always kept at the optimal drainage height. This eliminates the need for frequent manual adjustment by medical staff, greatly reducing the workload of medical staff, and also improving the automation and precision of the treatment process.

[0051] Optional, such as Figures 1 to 4 As shown, the height adjustment device for the lumbar drainage bag also includes an adjustment button 14; the adjustment button 14 includes a first adjustment button 141 and a second adjustment button 142. The adjustment button 14 is electrically connected to the drive component 23. The first adjustment button 141 controls the height adjustment component 20 to move to one end along the axial direction X of the support rod 11, and the second adjustment button 142 controls the height adjustment component 20 to move to the other end along the axial direction X of the support rod 11.

[0052] Specifically, the height adjustment device for the lumbar drainage bag also includes a first adjustment button 141 and a second adjustment button 142. The adjustment button 141 is connected to the drive component 23. The adjustment button 141 is used to control the drive component 23. The first adjustment button 141 and the second adjustment button 142 adjust the height adjustment component 20 in opposite directions along the axial direction X of the support rod 11 by controlling the drive component 23.

[0053] Understandably, adding the adjustment button 14 to the manually adjustable height adjustment component 20 further enhances the ease of operation for medical staff. In emergencies or special needs, medical staff can quickly adjust the height of the drainage bag directly using the manual button. Simultaneously, adding the manual adjustment button 14 serves as a backup adjustment method, ensuring the equipment still has adjustment capabilities in the event of a failure in the automated system. Even in extreme situations such as power outages or control system malfunctions, medical staff can maintain the normal adjustment of the drainage bag height manually, ensuring that the patient's treatment is not affected and increasing the reliability and stability of the equipment.

[0054] Optional, such as Figures 1 to 4 As shown, the height adjustment device for the lumbar drainage bag also includes an alarm 15, which is electrically connected to the gravity sensor 13.

[0055] Specifically, the height adjustment device for the lumbar drainage bag also includes an alarm 15, which is electrically connected to a gravity sensor 13. The alarm 15 can be triggered by sound or light signals, and this embodiment does not limit its use. When the gravity sensor 13 detects abnormal conditions such as the weight of the drainage bag attachment component remaining unchanged for a long period or changing too rapidly, it will promptly issue a signal to remind medical staff.

[0056] It is understandable that the alarm 15, electrically connected to the gravity sensor 13, can promptly alert medical staff to intervene and adjust the drainage status in case of malfunction or abnormality, ensuring the patient's treatment safety. At night or when medical staff are not near the patient, if any problem occurs with the equipment that affects the drainage effect or the patient's safety, the alarm can promptly issue a warning to attract the attention of those nearby, notifying medical staff to take measures and avoid harm to the patient due to failure to detect the problem in time.
